Snippetcove: a developer toolbox that runs entirely on your phone.
REGEX TESTER
- Paste a pattern and sample text and see matches and groups live
- Replace preview, ignore case, multiline and dotall flags
- Save patterns to a library and load them later
CONVERTER
- Convert between JSON, YAML and XML, with optional minified output
- Open a file or paste text. Nothing is uploaded
CODE SANDBOX
- A tiny scratchpad language with integers, let, print and basic maths, run on the device
FREE WITH ADS
- Every feature is free
- A banner at the bottom and a full-screen ad only sometimes after a successful action, never at launch; you choose how often in Settings
- Remove ads: monthly subscription or a one-time purchase. Removes ads only.
No account needed. Your patterns, text and files stay on this phone unless you copy or share them. Results are provided as they are, with no guarantee; test patterns and conversions in your own software before relying on them.
